Major storm to develop off New England's shoreline Monday night into Tuesday

Indications were strong enough on the potential of a Monday night into Tuesday storm from several days out to warrant putting it on Day 10 of my daily 10-day forecast on NECN's morning show. It's stayed there since, and signals are stronger than ever of a large storm developing off New England's coast. This storm will be packed with energy, and fed by the contrast of warm southern air and moisture, and arctic air streaming in from the north. Location of the storm will be critical, but consider the plot, below of forecast radar (left) and surface wind gusts (right). While this particular solution (NAM model guidance) suggests snow and up to 70 mph wind gusts, I'd never encourage planning on specific details at this point...but the important part of this is the idea of a storm with huge breadth - an expansive strong and potentially damaging wind field, and a large swath of precipitation with cold air in place for New England. The result could be not only heavy, wind-driven snow with blizzard conditions, but also damaging wind, coastal surf and coastal flooding. Again...it's early to determine exact impact, but when signals continue for several days consistently leading up to an event with the potential for such magnitude, it's important to sit up, take notice, and stay tuned to forecast updates.
